' SPECIFICATION forming part of Letters Patent No. 641,647, datedJanuary 16, 1900.

Application led April 12, 1899. v

To 'aZZ whom it may' concern,.-

Be it known that we, THOMAS L. QUIGLEY and PETER MALONE, citizens of theUnited States, residing at Boston, in the countyv of Suffolk and Stateof Massachusetts, have in-l vented new and useful Improvements in Carts,of which the following is a specification.

The object of our invention is to produce a strong, convenient, anddurable cart or vehicle which shall be capable of being turned around ina small space and in which the friction upon the main axle is reduced toa minimum.

The invention consists in a certain construction and combination ofparts, as fully set forth in the following specification andparticularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a perspective view of ourinvention as applied to a dumpcart, the pole beingshown broken off. Fig.2 is a longitudinal section of the same, the body of the cart beingshown tipped up in dotted lines. Fig. 3 is a section, partly inelevation, line 3 3, Fig. 2, looking toward the right in said figure.Fig. 4 is a plan and side elevation of the pole detached. Fig. 5 is aside elevation of a modified form of a portion of our improved cart, theaxle being shown in section.

Like numerals refer to like parts throughout the several figures of thedrawings.

In the drawings, 1 is the body of the cart, said body being hung uponthe U-shaped axle 2. Said axle 2 is supported upon the grooved wheels 33, which rotate upon the cylindrical portions 4 4 of the axle 2. Thewheels 3 3 are grooved upon their peripheries and bear upon tracks 5 5on the peripheries of the hubs 6 6 of the wheels 7 7. The wheels 7 7rotate in the usual manner upon the axle 8. The body 1 is reinforced onthe sides by plates 9 9, which are bolted to each other and to the body1 by the bolts 10 10 and to the vertical portions of the axle 2 by thebolts 11. To the bottom of the cart-body are bolted angle-irons 12, thevertical side of said angle-irons bearing against the vertical sides ofthe axles 2 and S. The lower ends of the angle-irons 12 Serial No.712,706. (No model.)

'said springs bearing against the front side of the axle 8 to preventthe same from rattling against the angle-irons 12 12.

The forward end of the body 1 rests upon a platform 15 and is lockedthereto to prevent the body from tipping up by the rod 16,which passesthrough the eyebolts 17, fast to the platform 15, in the usualwell-known manner. The platform 15 has a seat 18 thereon and a curvedfoot-rest 19 attached thereto.

The platform 15 is hinged at 42 to the angle-irons 12, so that when thebody 1 is tipped up to the position shown in dotted lines, Fig. 1, theplatform 15 remains horizontal.

Upon the under side of the platform 15 is fastened a hollow cylindricalflange 20, having a metal plate 21 upon its lower face. Said plate 21rests upon another metal plate 22 upon the upper face of the hollowcylindrical flange 23. To the under side of the flange 23 are fastenedtwo brackets 24 24, which have bearings 25 therein for the axle of thesingle front wheel 26. The flange 20 has angle-irons 27, fast to theinner face thereof, which turn outwardly at the bottom to engage theunder side of the plate 22, thus holding the platform 15 and flange 2Odown on the fiange 23. A cylindrical metal flange 28 is fastened to theouter face of the Hange 2O and projects downwardly therefrom to asufficient distance to engage the plate 22 on the lower flange 23, thusreceiving any end or sidewise thrust tending to separate the lowerIiange 23 and wheel 26 from the upper flange 20.

To the lower flange 23 are fastened two brackets 29, to which the pole30 is pivoted upon a bolt 31. The pole 30 is made in two A plate 37,bolted to the under side of 33, rests against the under side of 32 whenthe pole is in the position shown in Figs. 1 and 2.

One important feature of our invention is the manner in which we supportthe load of the body and its contents. It will be seen and understoodthat the larger part of the weight of the body of the cart and itscontents comes upon the wheels 3 3, and is thence transferred to thehubs G of the wheels 7, and as the wheels 3 rest upon the hubs 6 at apoint nearly over the point where the Atire of the wheel 7 rests uponthe ground it will be seen that the larger part of the thrust of saidweight will be taken directly through said wheels 7 and very littleweight will be brought to bear upon the axle 8. It will therefore beunderstood that there will be Very little friction upon the axle S atthe points thereof upon which the wheels 7 bear. It will also be seenand understood that, supposing the friction upon the bearings 4 to beequivalent to the friction of the wheels 7 upon the axle 8 when arrangedin the usual manner, the power required to turn the wheels 3 will beinversely as the diameters of the wheels 3 to the diameters of the hubs6 at the point where said wheels 3 bear thereon, or in the case of thecart illustrated in the drawings the power required to move the cart, asfar as friction of the axles is concerned, would be about onehalf thatrequired to move the cart constructed in the usual manner, the wheels 3being about twice the diameter of the hubs 6 at the point where saidwheels bear upon said hubs and rotating at one-half the speed of thewheels 7.

Another important feat ure of our invention is the single front wheeland the manner of attaching it to the cart-body. In the ordinaryconstruction there are two wheels swiveling upon a bolt attached to thewagon-body, and the whole strain of pulling the load comes upon thisbolt, which often gets worn or crystallized and breaks.

In our construction there is no possibility of an accident of this kind,as the fianges 20, 23, and 28 take all the pulling strain and are verystrong. It is evident that with a single wheel in front a cart can beturned very much more easily and in smaller space than where there aretwo front wheels. It is also evident that the pole is kept straight withmuch less strain and pull upon the horses where one wheel is used thanwhere two are used, for the reason that if the wheel is in the center ofthe cart and it strikes a rock or other obstruction it will ride up overit, whereas if there are two front wheels and one of them strikes a rockor other obstruction it will be thrown around, bringing a strain uponthe horses to keep the pole and wheels straight.

Still another feature of our invention is the jointed pole. It isobvious that the part of said pole can be folded back upon the part 32and the part 32 then turned up on the pivot 31 against the side of theplatform 15 and locked thereto to prevent the cart from being stolen orfor the sake of economizing space in the stable.

In order to lock the two parts 32 33 in line with each other, as shownin-Fig. 4, we provide a swivel-hook 38, which passes through a slot 39in the plate 37 and is then turned at right angles to said slot, thuslocking the two parts of the pole, as shown in said figure.

In Fig. 5 we have illustrated a modified form of our invention, in whichthere are on each side of the body 1 two wheels 40 40,which bear againstthe periphery of the hub G on the wheel 7 instead of one wheel 3 on eachside of said body.

The curved foot-rest 19 is another feature of our improved cart, theobject being to supply a foot-rest which shall present a firm footholdfor the driver whether the horses are pulling straight ahead or whetherthey are being turned around atan angle with the body of the cart.

In the foot-rest in ordinary use if the horses are turned at an anglewith the body of the cart the driver will be pulling in one directionupon the reins and his legs and feet will be pushing in a dierentdirection, resulting, oftentimes, in slipping and in all such cases in acomparative loss of power.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a cart, in combination, a body, an upper and a lower axle, a pairof wheels on each axle, the peripheries of the wheels on the upper axlearranged to bear upon the peripheries of the hubs of the pair of wheelson the lower axle, said body being fast to said upper axle andhavingasliding connection with said lower axle, substantially asdescribed for the purpose specified.

2.
